Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142358, here are decompositions:
- 31 + 142327 = 142358
- 61 + 142297 = 142358
- 127 + 142231 = 142358
- 199 + 142159 = 142358
- 367 + 141991 = 142358
- 397 + 141961 = 142358
- 421 + 141937 = 142358
- 487 + 141871 = 142358
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 142,358 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
